 * $Log: avrpio.h,v $
 * Revision 1.3  2005/07/26 16:06:20  haraldkipp
 * Added missing SPIDIGIO registers.
 *
 * Revision 1.2  2005/02/02 20:06:37  haraldkipp
 * This file will now contain the AVR port definitions, which were
 * previously specified in avr.h. This file will be included by avr.h,
 * so existing code should continue to run without change.
 *
 * Revision 1.1  2004/08/25 10:58:02  haraldkipp
 * New include directory cfg/arch added, which is used for target specific items,
 * mainly port usage or MCU specific register settings.

 * provides an overview of hardware resources in use.
 *
 * Values are geared to the Ethernut reference design and can be changed 
 * by the Configurator. This program creates a file with the same name
 * in the build tree, which replaces this placeholder.
